368 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [0. ornatus. 
Seemingly the more the leaves belong to the higher part of the adult plant the more 
they have a tendency to become cirriferous; it seems also that the 5 costae are 
more prominent in the leaflets of the radical leaves than in the upper ones. 
The armature of the leaf-sheaths is probably very variable according to the 
age of the plant and in the Javan form the sheaths appear generally very sparingly 
armed or even quite smooth. | 
I consider C. aureus Reinw. the same as C. ornatus, The authentic specimen 
of C. aureus which I have seen, is preserved in the Herbarium at Munich, and 
consists in a portion of the naked stem and an entire leaf, which is a radical one 
with a subterete petiole, 1:5 cm. in diam. at the base, and 1:20 m. long, armed 
with scattered straight spines. The rachis is feebly aculeate, and at the extremity is 
unarmed; the leaflets are exactly like those described by Martius, and in no way 
differ from those of the authentic specimens of C. ornatus; the two apical leaflets 
are not very large, and are shortly united at their bases; all are naked beneath and 
sparingly spinulous on the 5 robust costae of the upper surface. 
The home of Calamus aureus is said to be Celebes, but very likely that locality 
is- erroneous, as I have had occasion to state with respect to other species of Calamus 
collected by Reinwardt; and indeed in the Munich Herbarium the authentic specimen 
of C. aureus is labelled from Java and the handwriting is not that of Martius.

DzscniPTION.— Leaf-sheatAs glabrescent, powerfully armed with broad laminar lanceo- 
late spines, 2-3 cm. long, confluent by their bases and disposed in transversal 
rows, these 3-5 cm. apart. Radical /eaves with leaflets furnished with 5 distinct 
spinulous costae; the leaflets of the upper leaves less spinulous and less distinctly 
5- or at least 3- costate. 
Hasrrat.—The Malayan Peninsula. Griffith’s specimens were collected by E. 
Fernandez near Malacca at Durian Tungul, Father Scortechini gathered the same 
Palm in the district of Perak (No. 587°) and Sir G. King’s collector on the hills 
of Larut also in Perak at an elevation of between 50-150 metres (H. H. Calc. 
No. 3931). The Malay name in Perak is Rotang Mantang (Scortechini); “R. Ruga — 
Bodak” (Griffith ). 
OssERvATIONS.—Of Griffith’s specimen of C. ornatus I have seen only an inter- 
mediate portion of a leaf with 2 leaflets in the Kew Herbarium and another similar 
portion in that of Calcutta, nevertheless these specimens have been sufficient to 
establish their perfect identity with the more complete ones collected by Scortechini 
and by Sir G. King’s collector, 
In Griffith’s specimens the leaf-rachis is 13 mm. thick, triangular in section, 
and bifaced above with an acute and naked angle, slightly convex below and 
armed along the middle and at the sides with robust, solitary or subconfluent
